Abstract—The dependence of the impact strength and damping characteristics of сBN–Al composite materials on the specific surface (grain size) of cubic boron nitride powders has been investigated. The correlation between the damping characteristics of the composite material and its phase composition has been established. The dependence of the phase composition of the material on the specific surface of the powdered cBN component has been demonstrated. Composite materials with a biphasic structure and the highest density and hardness possible for this structure had the maximal impact strength.

电荷粒度对BN-Al复合材料冲击强度和阻尼特性的影响

摘要—研究了​​立方氮化硼粉末的сBN-Al复合材料的冲击强度和阻尼特性与比表面(粒度)的关系。已经确定了复合材料的阻尼特性与其相组成之间的相关性。已经证明了材料的相组成对粉末状cBN组分的比表面的依赖性。具有两相结构以及该结构可能的最高密度和硬度的复合材料具有最大的冲击强度。
